title: Linear erosive herpes simplex virus infection in immunocompromised patients: the "knife-cut sign".
abstract: Herpes simplex virus in immunocompromised patients may be misdiagnosed because of its atypical presentation. We present 3 cases of herpes simplex virus presenting as intertriginous fissures similar to the "knife-cut" ulcers associated with metastatic Crohn's disease. Our experience suggests that intertriginous fissures due to herpes simplex virus are recognizable patterns of viral infections in immunocompromised hosts.
